Felipe Giffu - PeerSpot reviewer

An operational system, similar to Linux where you can run your applications inside containers
With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers. When you mentioned using Nacula as part of your CI/CD pipeline, it means your application is deployed and managed automatically through the CI/CD process. Containers are used to deploy your application within this pipeline, but CoreOS does not run inside these containers. Instead, CoreOS is the base operating system that supports and manages these containers.

Offers easy management and container connection with HTTPS, but the support needs to improve
I have experience with the solution's setup in Rio de Janeiro, Brazil and our company has assisted in the development of a cluster in a research department, but we didn't start from scratch because we have IT professionals who have installed Kubernetes across 12 nodes of a cluster and a new environment can be created for a new platform. I also had another setup experience of Red Hat Advanced Cluster Security for Kubernetes in Portugal where I had to implement the solution in a cluster of 22 computer servers, which was completed with assistance from the IT department of the company. The initial setup process of the solution can be considered as difficult. The setup process involves using the permissions, subnets and range of IPs, which makes it complex. Deploying Red Hat Advanced Cluster Security for Kubernetes takes around eight to ten hours for new clusters. The solution's deployment can be divided into three parts. The first part involves OpenStack, where the cluster's resources need to be identified. The second part involves virtualizing assets and identifying other physical assets, for which OpenStack, Kubernetes, or OpenShift are used. The third part of the deployment involves dividing the networks into subnetworks and implementing automation to deploy the microservices using Helm. The number of professionals required for the solution's deployment depends upon the presence of automated scripts. Ideally, two or three professionals are required to set up Red Hat Advanced Cluster Security for Kubernetes.

Pros

"CoreOS Clair's best feature is detection accuracy."
"With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers."
"The most beneficial security feature of the product revolves around the areas of vulnerability and configuration."
"I like virtualization and all those tools that come with OpenShift. I also like Advanced Cluster Management and the built-in security."
"I am impressed with the tool's visibility."
"It is easy to install and manage."
"The most valuable feature is the ability to share resources."
"One of the most valuable features I found was the ability of this solution to map the network and show you the communication between your containers and your different nodes."
"The most valuable feature of the solution is its monitoring feature."
"The technical support is good."
 

Cons

"An area for improvement is that CoreOS Clair doesn't provide information about the location of vulnerabilities it detects."
"It can be improved in its support response. They usually take up to seven days to resolve the issue."
"The solution lacks features when compared to some of the competitors such as Prisma Cloud by Palo Alto Networks and has room for improvement."
"The initial setup is pretty complex. There's a learning curve, and its cost varies across different environments. It's difficult."
"The testing process could be improved."
"Red Hat is somewhat expensive."
"The documentation about Red Hat Advanced Cluster Security available online is very limited... So it's very limited to the documentation."
"I do see that some features associated with the IAST part are not included in the tool, making it an area where improvements are required."
"They're trying to convert it to the platform as a source. They are moving in the direction of Cloud Foundry so it can be easier for a developer to deploy it."
"The tool's command line and configuration are hard for us to understand and make deployment complex. It should also include zero trust, access control features and database connectivity."
 

Pricing and Cost Advice

"CoreOS Clair is open-source and free of charge."
"Red Hat offers two pricing options for their solution: a separate price, and a bundled price under the OpenShift Platform Plus."
"It's a costly solution"
"We purchase a yearly basis license for the solution."
"The price of Red Hat Advanced Cluster Security for Kubernetes is better than Palo Alto Prisma."
"The pricing model is moderate, meaning it is not very expensive."
